The Lodash library exported as a UMD module.

Lodash is released under the MIT license & supports modern environments.
Review the build differences & pick one that’s right for you.

Installation

In a browser:

<script src="lodash.js"></script>

Using npm:

$ npm i -g npm
$ npm i --save lodash

In Node.js:

// Load the full build.
var _ = require('lodash');
// Load the core build.
var _ = require('lodash/core');
// Load the fp build for immutable auto-curried iteratee-first data-last methods.
var fp = require('lodash/fp');

// Load a method category.
var array = require('lodash/array');
var object = require('lodash/fp/object');

// Load a single method for smaller builds with browserify/rollup/webpack.
var chunk = require('lodash/chunk');
var extend = require('lodash/fp/extend')

Note:
Don’t assign values to the special variable _ in the Node.js < 6 REPL.
Install n_ for a REPL that includes lodash by default.

Why Lodash?

Lodash makes JavaScript easier by taking the hassle out of working with arrays,
numbers, objects, strings, etc. Lodash’s modular methods are great for:

  • Iterating arrays, objects, & strings
  • Manipulating & testing values
  • Creating composite functions

Module Formats

Lodash is available in a variety of builds & module formats.
